SPRAYER.

Specification of Letters Patent.

Application filed June 1, 1909.

Patented July 4, 1911. Serial No. 499,385.

To all whom it may concern:

Be it known that I, MULFORD D. BUsKIRK,

a citizen of the United States, residing at Paw Paw, Van Buren county,Michigan, 5 have invented certain new and useful Improvements inSprayers, of which the following is a specification.

This invention relates to improvements in spraying apparatus.

My improved spraying apparatus is particularly designed and especiallyadapted by me for spraying grape vines, although it is desirable and maybe readily adapted for use in various other relations.

The main objects of this invention are: First, to provide an improvedspraying device, which is highly efficient, and, in spraying such vinesas grape vines, effectively sprays the entire vine. Second, to providean improved spraying apparatus which is very eflicient and at the sametime uses a minimum of the spraying solution. Third, toprovide animproved spraying apparatus, which is easy to manipulate. Fourth, to

provide an improved spraying apparatus,

which can be easily operated, so that the operator is protected from thespray. Fifth,

to provide an improved spraying apparatus which is very simple andeconomical in structure.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish theobjects of my invention by the devices and meansdescribed in the following specification.

The structure described constitutes one effective embodiment of myinvention. Other embodiments would be readily devised by those skilledin the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of thefeatures of my '45 invention is clearly illustrated in the accompanyingdrawing, forming a part of this specification, in which:

Figure 1 is a rear perspective view of a structure embodying thefeatures of my invention. Fig. 2 is an enlarged detail view of one ofthe arms of my improved spray head. Fig. 3 is an enlarged cross section,taken on a line corresponding to line 33 of Fig. 2.

In the drawing, similar reference characjwardly between the arms.

ters refer to similar parts throughout both views.

Referring to the drawing, 1 represents the running gear, which, in thestructure illustrated, is of the ordinary farm wagon type.

The tank 2 illustrated is of rectangular for adapted to fit the wagonbolsters. The top of the tank is adapted to serve as a platform for theoperator and driver, suitable seats being preferably provided, whichjecting delivery arms 9 thereon. These arms are provided with aplurality of oppositely-disposed horizontal nozzles 10, the

nozzles being adapted to deliver inwardly toward each other, as clearlyappears from the drawing, so that the head may be straddled over a vine,as is indicated in the drawing. I also preferably provide the pipe 8with a nozzle 9, arranged to deliver down- The pipe 8 is connected tothe pump by a flexible connection 11, so that it may be manipulated bythe operator to bring the same into proper 7 position over the vine orlift it over posts or the like. The sprayer is preferably supported by apair of supports 12, which have rests 13 and 14 for the pipe 8, the piperesting in the rest 13 of one support and being engaged in the rest 14of the other, as clearly appears from the drawing, so that it may beshifted longitudinally to keep the head in proper position over thevines, as the wagon is driven along at the side of the row. By this formof head, the nozzles delivering toward each other, the spray from onemeets that of the other at a central point creating a swirling movement,so that the vines are sprayed on all sides, and the blowing of the spraybeyond the vine largely prevented. It is found that, when the spray isdelivering from one side, a large portion is carried through and beyondthe vines and wasted; also, the force of the spray blows and holds theleaves to one side, so that only one side is effectively treated. Byarranging the nozzles on the head between the arms, the spray isprevented from rising, so that it settles to the ground about the vines,which is another very desirable feature.

It is found in practice that the apparatus can be used even when thereis considerable wind, which ordinarily prevents spraying, or preventsspraying when the common form of apparatus is used. This is also of verygreat advantage, as there are certain seasons or times during the yearwhen most satisfactory results are secured from the spray. A furtheradvantage is that the spray head may be shifted from one side of thewagon to the other, as conditions may require.

The spray head is preferably made up of sections of pipe connected bysuitable T- couplings in which the nozzles 10 are mounted, the nozzlesbeing threaded into the couplings so that they may be adjusted, ifdesired, as is indicated in Fig. 2.

My improved spraying apparatus is very simple and economical instructure, and is very eflicient in use, not only in that the vines arethoroughly sprayed, but that this is done with a minimum amount ofmaterial.

I have illustrated and described my im proved spraying apparatus in theform which I have found practical in use, the pump, engine and boilerbeing illustrated in conventional form. WVhile I have made use of asteam engine, an explosion engine could be utilized for the purpose,and, while I have illustrated the structure in detail in the form inwhich I have embodied it, I am aware that it is capable of very greatmodification in structural detail without departing from my invention,but, as these modifications will be apparent to those skilled in the artto which this invention relates, I have not attempted to illustrate ordescribe the same herein.

Having thus described my invention,what I claim as new and desire tosecure by Letters Patent is:
